In other words, async scripts run in the “load-first” order. How It Works: AJAX request starts. The page content shows up immediately: async doesn’t block it.

There’s no non-repetitive yet declarative way to download scripts quickly and asynchronously while controlling the execution order. Open source and radically transparent.

Because of that, if we were to run this in Chrome we would get this error: This is telling us there’s an issue on the only line in the external.js file: The external script is trying to select the div with the id of “changeMe” and change it’s innerHTML before it has been loaded in the browser so it errors out. The situation is depressing and you should feel depressed. "interactive" – the document was fully read.

This can be convenient if you’re going to wait for DOMContentLoaded anyway, but if you want to be really aggressive with performance, you can start adding listeners and bootstrapping sooner….

I am having a problem where the page is loading so fast, that jquery hasn't finished loading before it is being called by a subsequent script. Unfortunately it’s currently only supported in Chrome, and you have to declare which scripts to load twice, once via link elements, and again in your script. SP.SOD.executefunc('SP.UserProfiles.js','SP.UserProfiles',getUserProperties); will explicitly load this file if already not loaded. Mozilla wrote a great piece on the problem, cause scripts to execute in an unexpected order, everything that supports the async attribute. James Hibbard explains the pitfalls of implementing a sleep function in JavaScript, and digs into solutions for dealing with JavaScript timing issues. This is fine if they’re independent, perhaps “1.js” is a tracking script which has nothing to do with “2.js”. “2.js” won’t execute until “1.js” has executed (or failed to do so), “1.js” won’t execute until the previous script or stylesheet has executed, etc etc. In the above example, the browser will download both scripts in parallel and execute them just before DOMContentLoaded fires, maintaining their order. I’m going to load the scripts as if it weren’t there. Hey, got Twitch? Your browser may not support the functionality in this article.

The problem was tackled by JavaScript in a few flavours. Otherwise, perhaps not, stick with the simple end-of-body method. This will eliminate the error we are getting. // Create script element and set attributes, // Resolve the promise once the script is loaded, // Catch any errors while loading the script, // scriptToLoad will now be a reference to `window.Segment`. Specific algorithms to compute the LP-relaxation of the Set-Cover problem. Can employer legally stop paying time & 1/2 to exempt employee after stating in the offer that they would do so? The async IDL attribute controls whether the element will execute asynchronously or not. PHP Freaks Ok, cool, is the logic same if this code would go on a masterpage instead of an application page? We can just put our JavaScript at the bottom" And everyone was like, "Haha silly us, thinking that script tags belong in the header. By Grab the RSS feed and stay up-to-date. "complete" – the document was fully read and all resources (like images) are loaded too. Unfortunately there’s no declarative way to achieve this unless the scripts themselves are modified to track the loading state of dependencies.js. I would recommend that you read this post here on SP.SE: Use SP.SOD.executefunc('sp.js','SP.ClientContext',runthiscode); sorry but how can it make sure that it is loaded if we are not specifiying it in head tag to load it?

Some even used super-magic hacks, like LabJS.

Hurrah! Other browsers say: Ok, but I might not ignore “defer” on scripts without “src”. Well, if you’re dynamically deciding which scripts to load, yes, otherwise, perhaps not. A typical use of the plugin is to create a loading indicator when the AJAX call is in progress. I'm executing an external script, using a <script> inside <head>.

The holy grail is having a set of scripts download immediately without blocking rendering and execute as soon as possible in the order they were added.

Eww, there must be something better we can use now? Well organized and easy to understand Web building tutorials with lots of examples of how to use HTML, CSS, JavaScript, SQL, PHP, Python, Bootstrap, Java and XML. No, wait, come back! Other browsers in red say: I don’t understand this “async” thing, I’ll execute your scripts as soon as they land, in whatever order. A few tricks and minification later, it’s 362 bytes + your script URLs: Is it worth the extra bytes compared to a simple script include?
